Abstract: Objective: To evaluate the effectiveness of standardized cases(SC) in measurement of the nursing students' humanistc caring ability. Methods: A total of 100 practice nursing students were randomly divided into two groups(n=50 in each group). Group A adopted SC evaluation and group B assessment questionnaire by domestic scholars to determine their humanistic caring ability;then the satisfaction degree of the patients was investigated. The coincidence of their scores and the patients' satisfaction degree was compared and the effects of SC evaluation analyzed. Results: Group B achieved higher scores in questionnaires about health education, scientific solution of health problems and assistant meeting of the patients basic needs than group A in SC evaluation(P<0.05). Among the students with the score number of the first 15 and middle 20, the total score of humanistic caring ability of group B was higher than that of group A(P<0.01), while there was no statistical difference among students with the score number of last 15(P>0.05). The patient's satisfaction demonstrated no significant difference among students with different scores in humanistic care ability(P>0.05). The three nursing students with low satisfaction degree(average≤1) in group A were all among the last 15 in scores;However, the students with score number of the first 15 obtained higher satisfaction degree. Among the students with the score number of the first 15 in group B, only one got low satisfaction degree(average≤1). Conclusions: SC evaluation is accurate and effective in assessing the humanistic caring ability of the nursing students. It can be used as one of the standards in evaluating the students' humanistic caring ability before graduation and going to a post.
